because the outer electron structure in all of that element is similar, they have the same chemical and physical properties.

Answer: The correct answer is Option B.

Explanation:

Beryllium is the 4th element of the periodic table having electronic configuration [tex]1s^22s^2[/tex]. This element belongs to Group 2 of the periodic table.

Elements that belong to same group show similar chemical properties because they have same number of valence electrons.

For the given options:

Option A: Hydrogen

This element belong to group 1 of the periodic table.

Option B: Calcium

This element belong to group 2 of the periodic table. Thus, this will show similar chemical properties to beryllium.

Option C: Lithium

This element belong to group 1 of the periodic table.
